Specification of Letters Patent.

Application tiled February 8. 1907. Serial No. 356,492.

To all whom it may concern:

Be it known that I, Douixik BoLnnnL, a citizen of the United States, and resident of Oakland, Alameda county, and State of California, have invented new and useful Improven ents in Miners Pri specting-Tools, of which the following is a specification.

This invention relates to a prospecting implement for miners use, involving the sevoral features and functions of a pick for excavating, a wedge for splitting rock, a hammer for breaking specimens, and anax for cuttingroots and for like purposes.

The primary object of the invention is to provide for the use of the miner, when on a prospecting tour, a combination-tool that will take the place and fill all the uses of the different separate tools which are ordinarily required on a prospecting trip, and thereby materially reducing the load that the pros pector is compelled to carry.

A miners prospecting-tool of my invention consists of the several parts and features as lurreinafter described and claimed.

The accompanying drawing fully illustrates a miners prospecting-tool of my invention.

Figure 1 is a view of the head and handle of the tool, with the removable pick-points secured to the head when the tool is used as a pick; the head and the attached pick-point on one side are broken away to show the means for securing the head on the handle.

and the pick-point in the head. Fig. 2 is .a similar view of the separable head. and handle, with the pick-points removed. Fig. 3 is a top-view of Fig. 2, showing the head broken away in part on one side of the handle-socket. Fig. 4 is a side-view of the ax-blade detachet from the head. Fig. 5 is a view of the hammer-heal. is substituted for the pick-point or otl'ier detachable member. Fig. 7 illustrates the wedge removed from its handle, so tha'ljit may be secured in the head. in place of the pick-point or other detachable member.

A miners pros wcting-tool of my invention comprises the cast metal head 0 having a,

socket 2 for the handle I), and on opposite sides of thesocket and in the same plane, two bosses d d, with square ends 3. The

socket 2 tapers downwards, and the end of the handle is corres ondingly shaped, so as to be insertible from t 1e top ol the head. Each boss is also formed or provided with a socket 4 extending through it longitudinally from Fig. (i is a View of the wedge that;

the end or face 3 into the central socket 2.

From the underside of each boss also, a hole bosses d d letac'hmember is somewhat longer than the hole or socket in the boss, so as to extend into the central socket of the head, and in't'o the handle I), when that member is in place, ahole or cavity being formed in the handle to admit the end of the tang as seen in Fig. 1, where the wood of the handle and the metal of the head are cut away to show the tang in place. The tang thus has the double function of attaching the tool tothc head and of fastening the handle in .ljlie head. Each detachable member is secured in place by-its tang being inserted in the socket of the boss and secured by turning up the sercw a, after the detachable member is brought to a solid bearing against the end of the boss. When the points f-g are secured to the head a as shown in Fig. 1, the tool is converted into a pick; or by removing either or both points f the hatchet head It, or the wedge is, or the mallet m can be fixed in place.

By fixing the wedge 76 in the -supple' in'entary handle p, provided for that purpose, the wedge can be employed for splitting by Having thus described my invention, I claim:
